摘要
沿道路两侧构建的绿色防护带建设与道路系统融为一体,形成了四通八达的绿色通道网络,发挥着多种生态和景观功能。以北京大兴区京开路两侧的永久绿化带为研究对象,开展了间伐对人工林树木生长状况的影响研究。通过6年调查分析,结果表明:毛白杨间伐1/2,柳树全部伐除效果最佳,间伐后蓄积比对照增加56.18m3·hm-2,间伐林分的林木病虫害也得到了有效抑制。
Road system was integrated with the green protective belt which was built along the road on both sides. Connected network of green channel were formed,which plays a variety of ecological and landscape features.Taking permanent green belt on both sides of Jingkai Road in Daxing District of Beijing as the research object,the study of thinning on growth of the plantation were carried out.Through six years’investigation and analysis,result shows that thinning 1/2 Populus tomentosa + cutting all of the willows can obtain the optimal result;the timber volume increase 56.18 m3 ?hm-2 than that of CK after thinning;diseases and pests were inhibited effectively in the thinned stands.
